Abstract: Objective Objective To understand the cross?resistance of Culex pipiens pallens to common pesticides,so as to provide the evidence for improving the application of chemical pesticides. Methods Methods The IV instar larvae of DDVP?resistant,propoxur? resistant and cypermethrin?resistant strains as well as the sensitive strain of Culex pipiens pallens were collected to detect the re? sistance to DDVP,propoxur and cypermethrin based on the WHO bioassay method. Results Results The resistance coefficients of DDVP? resistant strain to DDVP,propoxur and cypermethrin were 14.47,8.96 and 207.27 respectively. The resistance coeffi? cients of propoxur?resistant strain to DDVP,propoxur and cypermethrin were 3.27,6.93 and 8.65 respectively. The resistance coefficients of cypermethrin?resistant strain to DDVP,propoxur and cypermethrin were 2.93,1.61 and 501.11 respectively. Con Con? ? clusion clusion The resistance and cross?resistance could be generated during the long?term application of a single kind of chemical pesticide,and we should pay more attention to the varieties and dosages of them.

摘要: 目的 目的 了解淡色库蚊对常用化学杀虫剂的交互抗性, 为合理使用化学杀虫剂提供依据。方法 方法 采用WHO生物 测定方法, 检测淡色库蚊敏感品系和抗敌敌畏、 抗残杀威、 抗氯氰菊酯3种抗性品系IV龄幼虫分别对敌敌畏、 残杀威和氯 氰菊酯3种化学杀虫剂的抗性。 结果 结果 淡色库蚊抗敌敌畏品系对敌敌畏、 残杀威和氯氰菊酯3种化学杀虫剂的抗性系 数分别为14.47、 8.96和207.27, 抗残杀威品系对上述3种杀虫剂的抗性系数分别为3.27、 6.93和8.65, 抗氯氰菊酯品系对 3种杀虫剂的抗性系数分别为2.93、 1.61和501.11。 结论 结论 长期使用一种化学杀虫剂易产生抗性, 并对其他化学杀虫剂 产生不同程度的交互抗性。使用杀虫剂时应注意选择药物品种和剂量, 以避免和延缓蚊虫抗药性的产生。
